This yellow drake dun hatched out of my aquarium over a month before her brethren in the wild are slated to emerge. She seems a bit small, and that might be the reason.

This mayfly was collected from the northeastern United States on May 13th, 2007 and added to Troutnut.com on May 18th, 2007.

Beautiful yellow drake

This is a fine specimen of one of the prettiest mayflies, Jason. She is small compared to some limestone specimens, but well within range for the species. I've collected varia males as small as 12mm, but many of the limestone females are 19-20mm. I think premature hatching is to be expected in aquaria.
